Lexus RX270 RX350 RX450h Front Air Spring Shock Absorber Assembly 48020-48071 48010-48071 OEM

Q1: Which OE numbers are for which side? Front Left: 48020-48070, 48020-48071, 48020-48075. Front Right: 48010-48070, 48010-48071, 48010-48075. These are side-specific units — never mix left with right.
Q2: Which vehicles does this fit? Lexus RX270 / RX350 / RX450h (AL10 third generation, 2008–2015) equipped with the factory air suspension option (amayama fitment lists RX270 / RX350 / RX450h, engines 2GR-FE / 2GR-FXE). Confirm the car actually has air suspension (option, not standard on all) by VIN.
Q3: What do the suffixes 48070 / 48071 / 48075 mean? They are successive revision numbers of the same side-specific strut. Per the genuine Toyota catalog, 48075 is the current replacement that supersedes 48070 and 48071. Match the number stamped on your original unit.
Q4: Is this the complete strut or just the air spring? The complete assembly — the genuine catalog name is "CYLINDER ASSY, PNEUMATIC, FRONT … W/SHOCK ABSORBER" (pneumatic cylinder with shock absorber), i.e. air spring and damper integrated into one unit, ready to install as a direct replacement.
Q5: Does this strut have electrical damping? The RX air suspension provides factory height control; whether your specific unit carries an electronic damping connector depends on the original equipment — confirm against the original unit by VIN before ordering.
Q6: Do I need to replace both front sides at the same time? Same-axle pair replacement is strongly recommended; an old unit on the other side causes uneven height and leveling behavior.
Q7: What should I pay attention to during installation? Release the air suspension pressure per the workshop manual; protect the air fitting and any electrical connector from dirt; after installation start the car and let the height control system re-level; check both sides' height and leaks before a road test.
Q8: Warranty policy and shipping damage? 18-month warranty under normal use. For shipping damage, inspect within 48 hours of receipt and send photos/video — the seller arranges a replacement.
Q9: Service life and maintenance? Depends on road conditions and climate. Keep the bellows clean and check for cracks during routine service; replace the complete unit if a bellows leak is found.
Q10: Are aftermarket alternatives available? No aftermarket cross numbers are currently listed in the European/aftermarket catalogs (spareto has no record; amayama lists no aftermarket alternative). For this series, genuine-OEM-style replacement is recommended — order the matched OE number by VIN.
